Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generating devices, and in particular to an aerosol generating device. Background Art

[0002] The aerosol generating device can heat the aerosol generating substrate to generate aerosol for the user to inhale. The current aerosol generating devices are roughly divided into two categories. One category heats a solid rod-shaped aerosol generating substrate to generate aerosol. The other category heats a liquid oil-like aerosol generating substrate (i.e., atomizing substrate). By adding the atomizing substrate to the aerosol generating device and using a heating core component to heat and atomize the atomizing substrate, an aerosol is generated.

[0003] Regardless of the type of aerosol generating device, current aerosol generating devices usually require a heating core assembly to heat the aerosol generating matrix. When some aerosol generating devices are working, the activation of the heating core assembly is controlled by a pressure switch. During transportation, complex environments may be encountered.

DETAILED DESCRIPTION

[0045] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0046] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0047] The end refers to the area at the end, which can be understood as an area with a certain length at the end, and is not limited to the end face.

[0048] In one embodiment, please refer to Figure 1 The aerosol generating device comprises a device housing 1, a heating core assembly 2, a conducting member 4, an elastic portion 5, a power source 9, a power supply circuit and a limiting structure 6. The heating core assembly 2, the elastic portion 5, the power source 9 and the power supply circuit are all arranged in the device housing 1.

[0049] The device shell 1 has an atomization space 21. The heating core assembly 2 is used to heat the aerosol generating substrate, and the generated aerosol enters the atomization space 21. The power supply circuit is used to conduct the heating core assembly 2 and the power supply 9, and the power supply 9 supplies power to the heating core assembly 2. In order to improve the safety of the aerosol generating device during transportation, the power supply circuit has a conducting member break. In one embodiment, as Fig.12 As shown, the conductive member break includes a first conductive contact 1101 and a second conductive contact 1102. The first conductive contact 1101 and the second conductive contact 1102 are in the power supply circuit, and the conductive member break is formed between the first conductive contact 1101 and the second conductive contact 1102. The conductive member 4 is used to conduct the first conductive contact 1101 and the second conductive contact 1102. Before the conductive member 4 conducts the first conductive contact 1101 and the second conductive contact 1102, the power supply circuit is always in a waiting state.

[0050] The conducting member 4 is movably arranged in the device housing 1, and has a waiting state and a connected state. In the waiting state, the conducting member 4 is disconnected from the conducting member break. In the connected state, the conducting member 4 is connected to the conducting member break to conduct the conducting member break, that is, the conducting member 4 conducts the first conductive contact 1101 with the second conductive contact 1102. At this time, if other positions on the power supply circuit are not disconnected, the power supply circuit is in a conducting state.

[0051] In order to keep the conducting member 4 in the ready-to-be-connected state, the limiting structure 6 in the present application locks the conducting member 4. The limiting structure 6 is configured to limit the conducting member 4 to the ready-to-be-connected state and keep the breaking end of the conducting member disconnected.

[0052] The elastic part 5 is used to provide elastic force to the conducting member 4 . After the restriction of the restricting structure 6 is released, the conducting member 4 can move to a connected state under the elastic force of the elastic part 5 .

[0053] The limiting structure 6 has a locked state and an unlocked state. When the limiting structure 6 is in the locked state, the conductive member 4 is locked to prevent the conductive member 4 from moving to the connected state, and the conductive member 4 remains in the ready-to-be-connected state. When the limiting structure 6 is in the unlocked state, the limiting structure 6 releases the restriction on the conductive member 4, so that the conductive member 4 moves to the connected state under the action of the elastic part 5.

[0054] The unlocking state of the limiting structure of the present application may be one state or multiple states that are sufficient to lock and hold the conducting member 4 .

[0055] When the conducting member 4 is in the waiting state, the conducting member break disconnects the power supply circuit, so that during transportation, even if the switch on the power supply circuit is accidentally started, the limiting structure 6 can maintain the position of the conducting member 4 when it is locked. When the aerosol generating device needs to be used, the limiting structure 6 is unlocked to be in the unlocked state, and the restriction on the conducting member 4 is released, so that the conducting member 4 is pushed to the connected state under the action of the elastic part 5. At this time, the conducting member break is connected, and the power supply circuit can work normally.

[0056] In one embodiment, there is no need to disconnect the conductive part again after the first use, so the limiting structure 6 is a disposable limiting structure, and the limiting structure 6 is used to be unlocked when the aerosol generating device is used for the first time. Disposable here means that the limiting structure 6 cannot be used a second time to restrict the conductive part to the waiting state.

[0057] In one embodiment, at least a portion of the restriction structure 6 is an operating portion 64 located outside the device housing 1 , and the operating portion 64 is used to operate the restriction structure. In one embodiment, the restriction structure 6 is disposed outside the device housing 1 .

[0058] In one embodiment, the heating core assembly works according to the frequency of the user's puffing, and the aerosol generating device includes a sensing module, which is used to sense the puffing state of the aerosol generating device. The sensing module is connected to the power supply circuit. In response to the sensing result of the sensing module, the power supply circuit can be connected or disconnected. When the sensing module senses that the aerosol generating device is puffed, the power supply circuit is connected in response to the sensing result of the sensing module. When the sensing module senses that the aerosol generating device is not puffed, the power supply circuit is disconnected in response to the sensing result of the sensing module. Specifically, the sensing result of the sensing module can be an electrical signal emitted after the target data is detected, or it can be an operation of directly disconnecting or connecting the power supply circuit in response to the puffing result of the aerosol generating device. That is, the sensing module can be either a sensor or a sensing switch.

[0059] Specifically, in one embodiment, the sensing module is an air pressure sensor, and the air pressure sensor is used to sense the gas pressure in the atomization space 21. The air pressure sensor is connected to the power supply circuit. After the gas pressure in the atomization space 21 is reduced to the target value, the air pressure sensor sends a connection signal, and the power supply circuit connects the circuit in response to the connection signal. When the gas pressure in the atomization space 21 is not reduced to the target value, the power supply circuit keeps the power supply circuit disconnected in response to the air pressure sensor. In some other embodiments, in addition to the air pressure sensor, the sensing module can also sense the changes in resistance, capacitance, voltage, etc. caused by inhaling the aerosol generating device to control whether to connect the power supply circuit.

[0060] For details, please refer to Figure 1 , Figure 2 and Fig.13 The air pressure sensor is a microphone 120, which is located on a power supply circuit. When the aerosol generating device is inhaled, the microphone 120 senses that the pressure in the atomization space 21 drops to a target value and then sends a signal, and the power supply circuit is turned on in response to the signal.

[0061] In some other embodiments, the heating core component can also be controlled by manual switch control. The aerosol generating device includes a manual switch for controlling the on and off of the power supply circuit. At this time, there is no need to collect the pressure value of the atomization space 21. The power supply circuit can be turned on or off as needed to start or stop heating the heating core component.

[0062] In one embodiment, please refer to Figure 1 and Figure 2 The conducting member 4 includes a locking fitting 45 and a conductive part 46 disposed on the locking fitting 45, and the locking fitting 45 is an insulating member. The conductive part 46 is used to connect the break of the conducting member, and the locking fitting 45 is used to cooperate with the limiting structure 6. The elastic force of the elastic part 5 on the conducting member 4 acts on the locking fitting 45, and the limiting structure 6 limits the conducting member to the waiting state by locking the locking fitting 45.

[0063] The locking fitting 45 and the conductive part 46 are of a separate structure for easy processing, and the conductive part 46 is made of a conductive material with a high cost, and the locking fitting 45 does not need to be conductive to reduce costs. In some other embodiments, the conductive part 4 can also be an integrally formed structure, in which case the conductive part 4 is entirely conductive. In some other embodiments, the locking fitting 45 and the conductive part 46 are insulated.

[0064] Specifically, in one embodiment, please refer to Fig.12 and Fig.13 The conductive part 46 includes an elastic conductive sheet 461, and the conductive part 46 is in conductive contact with the conductive member break through the conductive sheet 461. The conductive sheet 461 has a contact point 4611.

[0065] In one embodiment, the conductive part 46 includes a conductive plate, and the conductive sheet 461 and the conductive plate can be fixed together by integral molding, welding fixation, crimping fixation, etc. The two conductive sheets 461 on the conductive part 46 are in conductive contact with the first conductive contact 1101 and the second conductive contact 1102 respectively, so that the conductive part 46 is connected to the conductive member break, and the first conductive contact 1101 and the second conductive contact 1102 are conductively connected.

[0066] Please refer to Figure 4 , Figure 5 , Fig.14 and Fig.15 In one embodiment, the conductive member 4 includes a positioning rod 44 extending along the movement direction of the conductive member 4, and the positioning rod 44 is arranged on the locking fitting 45. The conductive part 46 has a positioning hole 462 for the positioning rod 44 to pass through. In one embodiment, the positioning rod 44 and the positioning hole 462 are interference fit to achieve the fixation of the conductive part 46. In some other embodiments, the conductive part 46 can be fixed by bonding, welding or clamping with the conductive member locking fitting 45. In one embodiment, please refer to Figure 4 , Figure 5 and Fig.15 The locking fitting 45 passes through the conductive portion 46 , and the conductive portion 46 has a through hole 463 for the locking fitting 45 to pass through.

[0067] Please refer to Figure 1 and Fig.12 The aerosol generating device includes a mounting base 8 and a circuit board 110 fixed on the mounting base 8, and the first conductive contact 1101 and the second conductive contact 1102 are both on the circuit board 110. In one embodiment, the circuit board 110 is fixed on the lower side of the mounting base 8. For details, please refer to Figure 3 and Figure 4 The mounting seat 8 includes at least two hooks 89 , and the circuit board 110 is fixed to the lower side of the mounting seat 8 under the action of the hooks 89 .

[0068] In one embodiment, please refer to Fig.12 , the first connection point 1103, the second connection point 1104, the third connection point 1105, and the fourth connection point 1106 on the circuit board 110. One pin of the heating core assembly is connected to the first connection point 1103, and the other pin is connected to the second connection point 1104. One of the positive and negative electrodes of the power source 9 is connected to the third connection point 1105, and the other is connected to the fourth connection point 1106. The third connection point 1105 is connected to the first connection point 1103.

[0069] The first conductive contact 1101 is connected to the fourth connection point 1106, and the second conductive contact 1102 is connected to the second connection point 1104. After the conductive portion 46 of the conductive member 4 is connected to the conductive member break, the first conductive contact 1101 is connected to the second conductive contact 1102, that is, the fourth connection point 1106 is connected to the second connection point 1104. In one embodiment, the direction of the wire between the circuit board 110 and the heating core assembly 2 is consistent with the direction of the gas path.

[0070] In one embodiment, please refer to Figure 1 and Figure 2 In order to facilitate user operation, the restriction structure 6 covers all or part of the air inlet 13 when in the locked state. Before unlocking, the restriction structure 6 covers all or part of the air inlet 13, making it easier for the user to understand that the aerosol generating device needs to be activated, thereby improving the user's experience. In some other embodiments, the restriction structure may not cover the air inlet.

[0071] Further, in one embodiment, please refer to Figure 1 and Figure 6 The limiting structure 6 includes a locking piece 61, and the limiting structure 6 covers the air inlet 13 through the locking piece 61. The locking piece 61 has a larger coverage area and can be applied to situations where the air inlet 13 is located at different positions. In addition, the locking piece 61 is easier for users to identify. The locking piece 61 is detachably connected to the locking fitting 45 of the conductive member 4, which is more convenient to unlock through the locking piece 61. The conductive member 4 can be unlocked by removing the locking piece 61, and the restriction on the conductive member 4 can be released. In one embodiment, one end of the locking piece 61 forms an operating portion for the user to operate to unlock the locking piece 61.

[0072] In some other embodiments, in addition to the locking piece 61, the limiting structure 6 can be any feasible method. For example, the limiting structure 6 can be connected to the locking fitting 45 of the conductive member 4 through a weak connection part. When unlocking is required, the limiting structure 6 can be destructively separated from the conductive member 4. For another example, a part of the conductive member 4 extends out of the device shell 1, and the limiting structure 6 is a tape that adheres and fixes the part of the conductive member 4 extending out of the device shell 1. For another example, the limiting structure 6 can be a clamping member that is clamped and fixed with the locking fitting 45 of the conductive member 4. This method will be described in detail below. For another example, the limiting structure can include a sliding member assembled on the device shell, the sliding member can slide horizontally relative to the device shell, the sliding member hooks the conductive member in the device shell, and when unlocking is required, the sliding member is pushed to separate the sliding member from the conductive member.

[0073] Further, in order to facilitate the locking of the conductive member 4, please refer to Figure 1 and Fig.16, the conductive member 4 has a restricted end 41, and when the conductive member 4 is in a waiting state, the restricted end 41 is locked by the restricting structure 6 and extends out of the device shell 1. When the conductive member 4 is in a connected state, the restricting structure 6 releases the lock on the restricted end 41, and the restricted end 41 returns to the device shell 1. The restricting structure 6 locks the restricted end 41 in the locked state to prevent the conductive member 4 from moving to the connected state. After the restricted end 41 extends out of the device shell 1, it is more convenient for the restricting structure 6 to lock the conductive member 4, and it is also convenient to unlock the conductive member 4. The retraction of the restricted end 41 does not affect the use of the aerosol generating device. Specifically, in one embodiment, the restricted end 41 is at the end of the locking fitting 45.

[0074] In some other embodiments, the restricted end 41 may also always be in the device shell 1. In this case, the restricting structure 6 needs to enter the device shell 1 to lock the restricted end 41. For example, the restricted end 41 has a lock hole, and the restricting structure 6 includes a lock hook hung on the device shell 1. The lock hook hooks the lock hole to prevent the conductive part 4 from moving to the connected state. When unlocking is required, the lock hook is removed from the restricted end 41. This implementation requires sufficient operating space to be reserved on the device shell 1.

[0075] Further, in one embodiment, please refer to Fig.16 The restricted end 41 has a locking hole 411 or a locking slot, and the locking hole 411 is inserted into the locking structure 6 in the locked state. When in the locked state, the limiting structure 6 is blocked by the restricted end 41 and the device shell 1, preventing the conductive member 4 from moving to the connected state. In one embodiment, the limiting structure 6 adopts a locking plate 61. In some other embodiments, the limiting structure 6 can also adopt other structures such as a locking rod and a locking block. In some other embodiments, the locking hole can also be replaced by a locking slot.

[0076] In addition to the above-mentioned method of directly clamping the conductive member 4 by the clamping structure, the conductive member 4 can also be clamped on the device shell 1. For example, in one embodiment, the conductive member 4 includes an elastic arm 42 and a clamping structure 43. The clamping structure 43 is at the end of the elastic arm 42. The device shell 1 has a conductive member lock hole 14, and the elastic arm 42 extends into the conductive member lock hole 14. The clamping structure 43 is clamped on the device shell 1, and the clamping structure 43 and the device shell 1 are blocked to prevent the conductive member 4 from moving to the connected state. When the limiting structure 6 is in the locked state, it is blocked with the clamping structure 43 to limit the bending deformation of the elastic arm 42. When the limiting structure 6 is in the unlocked state, the elastic arm 42 can be elastically deformed to release the blocking relationship between the clamping structure 43 and the device shell 1. The clamping structure 43 is clamped on the device shell 1, including being clamped in the conductive member lock hole 14 or the edge of the outer opening of the conductive member lock hole 14.

[0077] For details, please refer to Figure 4In one embodiment, the holding structure 43 is at the restricted end 41, and the holding structure 43 extends out of the device housing 1 when the conducting member 4 is in the ready-to-connect state. The elastic arm 42 and the holding structure 43 at the end of the elastic arm 42 are both part of the locking fitting 45.

[0078] Further, in order to enable the conductive member 4 to automatically move to the connected state after the restriction structure 6 releases the restriction on the elastic arm 42, in one embodiment, please refer to Figures 1 to 5 At least one of the holding structure 43 and the blocking portion on the device shell 1 that blocks the holding structure 43 has a guiding slope surface that guides the elastic arm 42 to deform to release the holding relationship with the device shell 1. Specifically, the guiding slope surface can be an inclined surface, an arc surface, or a curved surface.

[0079] In one embodiment, please refer to Figure 4 The holding structure 43 on the elastic arm 42 is a holding protrusion 431, and a guiding slope 432 is provided on the holding protrusion 431. Correspondingly, the outer opening of the conductive member lock hole 14 is expanded, and at this time, the edge of the conductive member lock hole 14 has a guiding slope 141. The guiding slope 432 on the holding protrusion 431 cooperates with the guiding slope 141 at the edge of the outer opening of the conductive member lock hole 14. Under the action of the elastic force of the elastic part 5, the elastic arm 42 can be deformed, and then the holding protrusion 431 is separated from the holding relationship with the edge of the opening of the conductive member lock hole 14, so that the conductive member 4 is unlocked.

[0080] For further information, please refer to Figures 3 to 5 , at least one elastic arm 42 is a first elastic arm 421, at least one elastic arm 42 is a second elastic arm 422, and the limiting structure 6 includes a blocking portion 62 between the first elastic arm 421 and the second elastic arm 422, and the blocking portion 62 prevents the first elastic arm 421 and the second elastic arm 422 from approaching each other. The first elastic arm 421 and the second elastic arm 422 are arranged relative to each other, which is conducive to the force balance of the conductive member 4, and the resistance of the conductive member 4 during movement is small, and it is easier to be unlocked. Specifically, in one embodiment, the holding structure 43 on the first elastic arm 421 is on the side of the first elastic arm 421 facing away from the second elastic arm 422, and the holding structure 43 on the second elastic arm 422 is on the side of the second elastic arm 422 facing away from the first elastic arm 421. Under the action of the blocking portion 62, the holding structures 43 on the elastic arms will not approach each other.

[0081] For details, please refer to Figures 3 to 6, the conductive member 4 has two elastic arms 42, namely, a first elastic arm 421 and a second elastic arm 422. The limiting structure 6 is a locking plate, and there are two locking holes 63 on the locking plate 61, for the first elastic arm 421 and the second elastic arm 422 to enter respectively. The portion between the two locking holes 63 is a blocking portion 62, which prevents the first elastic arm 421 and the second elastic arm 422 from approaching each other, thereby preventing the conductive member 4 from being unlocked. Specifically, in one embodiment, the first elastic arm 421 and the second elastic arm 422 are both part of the locking fitting 45.

[0082] In one embodiment, please refer to Figure 2 , the conducting member lock hole 14 is an air inlet hole 13 that is connected to the atomizing space 21 and can supply air to the atomizing space 21. In this way, the conducting member lock hole 14 can be fully utilized to make the air intake of the device smoother. In some other embodiments, the conducting member lock hole 14 can also be sealed with the conducting member 4, and at this time, external gas cannot enter the atomizing space 21.

[0083] In one embodiment, the aerosol generating device generates aerosol using an atomizing substrate. The heating core assembly 2 includes an electrically heated atomizing element for heating the atomizing substrate. Figures 1 to 5 The device shell 1 has an oil storage space 11, and the oil storage space 11 is used to store the atomized matrix, and the atomized matrix is ​​heated and atomized to generate an aerosol. In some other embodiments, the aerosol generating device can also heat a solid rod-shaped aerosol generating matrix.

[0084] The atomization space 21 is in the heating core assembly 2, and the heating core assembly 2 has an oil inlet 22 for the atomization matrix to enter. After the electric heating atomization element is energized, the atomization matrix is ​​heated and atomized to generate an aerosol. Since external gas needs to enter the atomization space 21 when the atomization space 21 is sucked, the device shell 1 has an air inlet 13 connected to the atomization space 21, so that when the aerosol in the atomization space 21 is sucked, the external gas can enter the atomization space 21 through the air inlet 13 to replenish the gas.

[0085] In order to facilitate the transportation of the aerosol generating device and prevent the oil in the oil storage space 11 from leaking out through the heating core assembly 2, the heating core assembly 2 in the present application needs to be activated before the first use. Only after activation will the atomization space 21 of the heating core assembly 2 be connected to the oil storage space 11.

[0086] The heating core assembly 2 includes at least a dormant state and an awakening state. In the dormant state, the oil inlet 22 is closed, and the atomized matrix cannot enter the atomizing space 21 through the oil inlet, thereby isolating the atomizing space 21 from the oil storage space 11. In the awakening state, the oil inlet 22 is opened and communicated with the oil storage space 11, thereby communicating the atomizing space 21 with the oil storage space 11, and the atomized matrix can enter the atomizing space through the oil inlet 22.

[0087] In order to activate the heating core assembly 2 and simplify the structure of the aerosol generating device, the heating core assembly 2 is on the movement path of the conductive part 4 from the connected state to the to-be-connected state. When the conductive part 4 moves from the to-be-connected state to the connected state, it can drive the heating core assembly 2 to move from the sleep state to the awakened state.

[0088] In this way, during transportation, the heating core assembly 2 is in a dormant state, the oil in the oil storage space 11 cannot flow into the heating core assembly 2, and the atomized matrix is ​​not easy to leak through the atomization space 21. The limiting structure 6 can maintain the position of the conductive member 4 when it is locked. When the aerosol generating device needs to be used, the limiting structure 6 is unlocked to unlock the limiting structure 6, which can release the restriction on the conductive member 4, so that the conductive member 4 is driven to the connected state under the action of the elastic part 5, and the heating core assembly 2 is pushed to the awakened state. At this time, the atomization space 21 of the heating core assembly 2 is connected with the oil storage space 11, and normal atomization can be performed.

[0089] In one embodiment, the conducting member 4 of the aerosol generating device is disposed on the lower side of the heating core assembly 2, and the conducting member 4 can move upward to a connected state. When the conducting member 4 moves upward from the waiting state to the connected state, the heating core assembly 2 is driven to move from the dormant state to the awakened state.

[0090] The top of the device shell 1 is provided with a suction hole 12 for the user to inhale the aerosol. The atomization space 21 is in communication with the suction hole 12, so that the aerosol generated in the atomization space 21 can be sucked through the suction hole 12. In one embodiment, the atomization space 21 extends up and down, the upper end of the atomization space 21 is in communication with the suction hole 12, and the lower end is for the gas to enter after entering the device shell 1 through the air inlet 13.

[0091] The limitations of directional words such as top, bottom, up, and down in this application are for ease of understanding. The description made when the aerosol generating device is in use is only used to reflect the relative position relationship between the structures. When the aerosol generating device is in other postures, the directional words in this application should be understood after switching to the use state.

[0092] The conductive member 4 is abutted against the heating core assembly 2, and the above-mentioned changes in the awakening state and the dormant state are brought about by changing the abutting position of the conductive member and the heating core assembly. The heating core assembly 2 is provided with an oil inlet 22, and in the dormant state, the oil inlet 22 is closed, and the oil in the oil storage space 11 cannot flow into the heating core assembly 2.

[0093] In some other embodiments, the conducting member 4 and the heating core assembly 2 may also be fixedly connected or hinged.

[0094] Specifically, in one embodiment, please refer to Figure 1 and Fig.14 , the locking fitting 45 contacts the heating core assembly 2, and the conductive part 46 does not contact the heating core assembly 2 to avoid damage. When the conductive part 4 moves upward from the waiting state to the connected state, the locking fitting 45 pushes the heating core assembly 2 upward to move to the awakening state.

[0095] The aerosol generating device includes a seal 3, the seal 3 seals the bottom of the oil storage space 11, and the heating core assembly 2 is sealed with the seal 3. Please refer to Figure 1 and Figure 2 When the heating core assembly 2 is in a dormant state, the oil inlet 22 and the oil storage space 11 are separated by the seal 3, so that during transportation, the atomized matrix in the oil storage space 11 cannot enter the heating core assembly 2 through the oil inlet 22, and the atomized matrix is ​​not easy to leak through the atomization space 21 and the air inlet 13.

[0096] Regarding the oil storage space 11, the shape of the oil storage space 11 can be in any feasible manner, for example, the heating core component 2 passes through the oil storage space 11, and the oil storage space 11 is annular at this time. For another example, the oil storage space 11 can also be on one side of the heating core component 2.

[0097] Regarding the structure of the heating core assembly 2, in one embodiment, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The heating core assembly 2 includes an assembly housing 23 and a first atomizing seat 24, the assembly housing 23 is fixed to the first atomizing seat 24, and the first atomizing seat 24 has a first atomizing seat hole 241 on the side wall thereof, which is connected to the atomizing space 21. The heating core assembly 2 also includes a first oil-conducting cotton 25 and a second oil-conducting cotton 26. The first oil-conducting cotton 25 and the second oil-conducting cotton 26 are both made of porous materials, such as porous oil-absorbing cotton. There is an assembly inner frame 28 between the first oil-conducting cotton 25 and the second oil-conducting cotton 26. The heating core assembly 2 also includes a second atomizing seat 27, which is fixed to the bottom of the assembly housing 23 and fixed to the bottom of the assembly inner frame 28. The electrically heated atomizing element is on the inner side of the second oil-conducting cotton 26. The atomizing matrix enters the first oil-conducting cotton 25 through the oil inlet 22, and then enters the second oil-conducting cotton 26 through the assembly inner frame 28, and is heated and atomized after contacting the electrically heated atomizing element to produce an aerosol. The electrically heated atomizer may be in any feasible form, such as a heating wire mesh, a plurality of parallel heating wires, etc.

[0098] In one embodiment, please refer to Figure 1 , Figure 2 and Fig.11The seal 3 is annular, and the through hole 31 in the center of the seal 3 is for the heating core assembly 2 to pass through. When the heating core assembly 2 is in the dormant state, the oil inlet 22 of the heating core assembly 2 is blocked by the hole wall of the through hole 31, so that the oil storage space 11 is separated from the oil inlet 22. The outer peripheral surface of the seal 3 is sealed with the inner wall surface of the device shell 1. In some other embodiments, there can be multiple seals, such as a bottom plate at the bottom of the oil storage space, and the seal at the bottom plate and the heating core assembly is sealed with the heating core assembly, and the seal at the bottom plate and the device shell does not contact the heating core assembly.

[0099] In one embodiment, please refer to Figure 1 and Figure 2 A lining plate 7 is mounted above the seal 3, and the lining plate 7 can limit the seal 3 from deforming into the oil storage space 11.

[0102] The coil spring is also in a compressed state when the heating core assembly 2 is in a dormant state or an awakened state. In this way, the coil spring can not only provide a force to the conductive member 4, but also after activation, the coil spring can still exert a certain force on the conductive member 4 to maintain the stability of the conductive member 4 and the heating core assembly 2. In some other embodiments, the coil spring can be in a compressed state only when it is in a waiting state. In some other embodiments, the elastic part 5 can be elastic rubber, a reed, etc. in addition to the coil spring.
